wait for the engine to cool
Remove the radiator cap ONLY when the engine is cold.
If it is clean, undamaged, and in good working condition.....NO. Since the radiator needs to be removed, to remove the engine, now is a good time to have it cleaned and checked.
* With the engine cold remove the radiator cap * Move a large container under to catch the coolant as you drain it * Drain the radiator by opening the drain plug at the bottom on the left side
Pour it into the expansion bottle not the radiator type cap on the engine, opening that will give you steam burns if the engine is hot.
The radiator does not have a cap as most cars do. You add coolant to the reservoir bottle. The reservoir bottle may be under pressure when the engine is warm. Use caution when opening.
No, you do not have to remove the engine to replace a radiator hose.No, you do not have to remove the engine to replace a radiator hose.
if i am not mistaken there is no "raditor cap" The cap that vents the radiator is on the overflow canistor. usually plastic, usually black. use the same safety precautions, getting burnt in not uncommon. do this when the engine is cold if possible. hope it helps. duboff
In the engine and radiatorIn the engine and radiator
The fan should run when the engine reaches a set temperture. If it does not and the engine is overheating, check the thermal relay.
The cooling system is under pressure and opening the cap can spray you (and other things) with very hot coolant.
You can turn on the heater as that will cool the coolant more. If the car is sitting still and off, opening the hood will help. If you have a hose available..spraying the radiator with help drop the coolant temperature by increasing the radiator's efficiency.
Actually, both are used. However, it is more common to pull air through the radiator towards the engine. This draws cooler outside air through the radiator. Pushing air from the engine towards the radiator means that you are pulling hot air from around the engine towards the radiator.
